A)a 0.05 kg mass is used to accelerate a cart. at t=1 second, the 0.5 kg cart is at x=0.5 m, at rest. at t=2.5 seconds, the cart is at 1.5 m, traveling at 1.3 ± 0.3 m/s. calculate and compare the impulse with the total change in momentum of the cart and mass. (read the theory and sections 1.5 through 1.7 if youâre not sure how to do this.)
b) what would be the effect of air resistance and friction on the final velocity and momentum of the cart?
c) if a cart of mass 1.2 kg, traveling at 0.5 m/s, collides elastically with a cart of mass 0.7 kg, initially at rest, what is the final velocity of the first cart?
d) if the two carts above stick together after the collision, what is the final velocity of the first cart?
e) what is the final velocity of the first cart in (c) if the second cart has mass 1.8 kg?
f) what is the final velocity of the first cart in (d) if the second cart has mass 1.8 kg?

Does anyone know how to solve this problem? i really need . i made an attempt but i just cant get it. a metal rod is 25.000 cm long at 25.0 degrees celsius. when heated to 102.0 degrees celsius, it is 25.054 cm long. what is the coefficient of linear expansion for this metal.
